Generic character. Cephalon produced and depressed ante- 

 riorly. Eyes coalesced into one, situated above and anterior to 

 the superior antenusB. Superior antennae without a secondary 

 appendage. Gnathopoda subchelate, carpi antero-distally pro- 

 duced to the extremity of the inferior margin of the propoda. 

 First pair more robust than the second. Second having the 

 propodos longer than the propodos of the first pair. Posterior 

 pair of pereiopoda much longer than the others. Posterior pair 

 of pleopoda biramous. Telson squamiform, entire. 



The head is rounded above, and the anterior dorsal 

 surface is considerably produced and depressed. The 

 eyes are deep-seated, converging together, so as to ap- 

 pear to be but a single organ, placed horizontally above, 

 and still more forward than the base of the superior pair 

 of antennas. The antennas are simple in their character, 

 the superior pair not being furnished with a secondary 

 appendage. The mandibles are furnished with an ap- 

 pendage. The first two pairs of legs are complexly 

 subchelate, having the wrist produced anteriorly along 

 the inferior margin of the hand, which is much longer 

 and not so broad in the second as in the preceding pair 

 of legs. The last pair of legs are considerably longer 

 than any of the other pairs, and terminate in a long
